Description

Technical Field

[0001] This utility model relates to the field of pipe fixing technology, specifically a pipe welding fixing device. Background Technology

[0002] Existing pipeline structures often require multiple connections for use, necessitating pipe butt joints and welding for fixation. This process involves multiple welding assemblies to complete the pipeline laying. During welding, it is often necessary to fix the two pipes first before welding to effectively prevent pipe shaking and misalignment during the welding process. Furthermore, during welding, the two pipes need to be rotated to prevent welding operations from being impossible on the outer wall section at the bottom of the pipe. Therefore, a pipe welding fixing device is needed to solve the above problems. Utility Model Content

[0005] Preferably, the width of the lifting cavity is adapted to the width of the placement platform, and the placement platform moves up and down within the inner wall of the lifting cavity.

[0006] Preferably, the telescopic motor has a telescopic shaft connected to its telescopic power output shaft, and the telescopic shaft is fixedly connected to the center of the bottom of the placement platform.

[0011] Preferably, a tightening motor is installed on the outer wall of the mounting plate, and a small rotating shaft is fixedly connected to the power output shaft of the tightening motor.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This pipe welding fixing device, by setting up a circular roller, a pipe to be processed, a connector, an elastic band, etc., allows the pipe to be processed to be placed on top of the circular roller, and the elastic band on the device covers the top of the pipe to be processed.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5 A fixing device for pipe welding includes: a welding table 1, a support column 2 connected to the bottom of the welding table 1, a lifting cavity 3 formed in the inner wall of the welding table 1, an extension wall 4 fixedly connected to the inner wall of the welding table 1, a telescopic motor 5 provided at the bottom of the welding table 1, a telescopic shaft 6 connected to the outer wall of the telescopic motor 5, a placement platform 7 connected to the top of the telescopic shaft 6, a fixing device 8 installed on the outer wall of the placement platform 7, a roller 9 provided on the inner wall of the fixing device 8, a rotary motor 10 installed on the outer wall of the fixing device 8, a rotating shaft 11 connected to the outer wall of the rotary motor 10, a pipe to be processed 12 on the outer wall of the roller 9, a lifter 13 installed on the outer wall of the welding table 1, a connector 14 installed on the outer wall of the welding table 1, an elastic band 15 connected to the outer wall of the connector 14, and an installation piece 16 connected to the outer wall of the welding table 1.

[0018] The width of the lifting cavity 3 is matched with the width of the placement platform 7, and the placement platform 7 moves up and down in the inner wall of the lifting cavity 3. The placement platform 7 is movably connected to the inner cavity of the lifting cavity 3, so that when the pipe to be processed 12 is placed on the top of the placement platform 7, the placement platform 7 can be raised in the inner cavity of the lifting cavity 3 when needed, and the height of the pipe to be processed 12 is increased.

[0019] The telescopic motor 5 has a telescopic shaft 6 connected to its telescopic power output shaft. The telescopic shaft 6 is fixedly connected to the bottom center of the placement platform 7. The telescopic motor 5 outputs telescopic power, causing the telescopic shaft 6 to enter the telescopic state. The other end of the telescopic shaft 6, away from the telescopic motor 5, is connected to the placement platform 7, so that the placement platform 7 is driven by the lifting and lowering of the telescopic shaft 6.

[0020] Among them, there are several fixtures 8 and rollers 9, and several fixtures 8 and rollers 9 are symmetrically arranged in pairs on the surface of the placement platform 7. The fixtures 8 on the device are installed on the surface of the placement platform 7 and are symmetrically arranged, so that each roller 9 on the device corresponds to a fixture 8, thereby arranging the fixtures 8 and rollers 9 on both sides of the surface of the placement platform 7.

[0021] The rotary motor 10 has a rotating shaft 11 connected to its power output shaft. The rotating shaft 11 passes through the inner wall of the fixture 8 and the roller 9. When the rotary motor 10 outputs rotational power, it drives the rotating shaft 11 to rotate. The outer wall of the rotating shaft 11 is connected to the roller 9. The rotating shaft 11 and the roller 9 rotate synchronously, thus putting the roller 9 into a rotating state.

[0022] The outer wall of the circular roller 9 overlaps with the pipe 12 to be processed, and four circular rollers 9 are set at the bottom of the same pipe 12 to be processed. When the pipe 12 to be processed is placed on the device, the four circular rollers 9 on the device support the bottom ends and sides of the pipe 12 to be processed. When the circular rollers 9 are in the state, the pipe 12 to be processed on the device is supported and rotated by the rotation of the circular rollers 9.

[0023] The number of connectors 14 is four, and the four connectors 14 are symmetrically arranged on both sides of the surface of the welding table 1. The connectors 14 on the device are symmetrically arranged on the surface of the welding table 1, so that the left side of the elastic band 15 on the device is fixedly connected to the outer wall of the connector 14, and the right side extends beyond the outer wall of the connector 14. The connector 14 is used as a pressure roller, so that the elastic band 15 on the device is controlled by the tightening motor 17 at the mounting plate 16.

[0024] The outer wall of the mounting plate 16 is equipped with a tensioning motor 17, and a small rotating shaft is fixedly connected to the power output shaft of the tensioning motor 17. When the tensioning motor 17 outputs rotational power, the rotating shaft of the tensioning motor 17 drives the elastic band 15 to perform winding or unwinding operations, and changes the length of the elastic band 15, so that the elastic band 15 on the device affects the surface of the pipe 12 to be processed.

[0025] The working principle involves first setting up a circular roller 9, a pipe 12 to be processed, a connector 14, and an elastic band 15. When the pipe 12 is placed on top of the circular roller 9, the elastic band 15 covers the top of the pipe 12. As the elastic band 15 retracts at the end past the connector 14 under the influence of the tightening motor 17, it continuously adheres to the outer wall of the pipe 12, thus binding the pipe 12 effectively during tightening. Then, a lifting device 1 is set up... 3. The structure of the rollers 9, the pipe to be processed 12, and the placement platform 7 allows the pipe to be processed 12 to be placed from outside the device onto the device. The pipe to be processed 12 is pushed from the inner wall of the lifter 13 to move towards the middle position of the device. When the pipe to be processed 12 is pushed to the top of the four rollers 9, the placement platform 7 is lifted by the telescopic power and the pipe to be processed 12 is raised and lowered synchronously. Thus, the pipe to be processed 12 on the device is supported by the four rollers 9. Then, the rotary motor 10 controls the rollers 9 to rotate the pipe to be processed in a circular motion.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
